Abstract (en)
[origin: EP0120526A2] A sine bar mechanism comprises an arm (9) of radius R which is pivoted about an axis (13) which is also the axis of a diffraction grating. An elongate member (6) is pivotally mounted at one end (7) and is pivotally connected to the arm (9) at its other end (8). The co-ordinates (x,y) of the point (7) and the length of the elongate member (6) are chosen to optimise the characteristics of the mechanism. Embodiments in which the elongate member (6) comprises a lead screw and the pivotal connection (8) comprises a nut which is pivotally mounted on the arm (9) and which engages with the lead screw are described and their use in various types of monochromator portrayed.
